Tire wear estimation system, tire wear estimation program and tire wear estimation method

摘要

PROBLEM TO BE SOLVED: To provide a tire wear amount estimation system, a tire wear amount estimation program and a tire wear amount estimation method capable of achieving high wear amount estimation accuracy even when traveling at a low speed. A tire wear estimation system includes a step of acquiring a strain signal output from a strain sensor 115 provided on the inner surface or inside of a pneumatic tire 10 and a ground contact area of a tread portion corresponding to the strain sensor 115. This includes a step of estimating the wear state of the tread portion of the pneumatic tire 10 based on the distortion signal (Bo) output at the timing of kicking out from the road surface of Ac and the reference value of the distortion signal.
